' Application filed March 9, 1915. Serial no. 13,130;

To all whom it may concern:

Be it known that 1, ANDREW O; BURGESS, a citizen of the United States, and a resident of Newark, county of Essex, and State of New Jersey, have invented certain new and useful Improvements in Writing Implements, of which the following is a specification.

This'invention relates to writing implements and is arranged to provide a pen consisting of pen points, pen points in this The pen points are arra ed so that they *O can be alternately available and are preferably arranged in nested form, although a close nesting is not absolutely essential, and such nesting pens are arranged to slidelongitudinally and can be alternately nested one in front of the other, this being usuallyaccomplished by sliding one of the pens back and forth on the other, the other pen being fastened to the holder and the sliding pen mounted thereonand adapted to be either projected forward to have its points project in front of the point of the main point, or to have its points withdrawn and held in rear of the points of the main pen.

T he invention has one type illustrated in the accompanying drawing, in which Figure 1 is a top view of the improved. pen showing the pen points in full lines with the main pen available for writing, and showing in dotted outline the second pen point available for use. Fig. 2 is a section on line 22, in Fig. 1.

It will be understood that it is not essential to make the pen identical with the illustrated form, and numerous changes can be made as to the shape and proportion of the parts and their relative dispositions without departing from the scope of the invention. In the form shown the main point 10 is of the ordinary form of pen so far as its Specification of Letters Patent.

rear end and its writing point are concerned,

' the rear end 11 being adapted to be suitably fastened to a holder, the usual form being arc-shaped so that it fits into a round end of a holder and it'has on its forward end the nibs or points 12 which, in the type illus-' trated, are broad or of the stub type to permit fairly heavy and rapid writing by the user, so thatthe pen used by itself is adapted for, ordinary correspondence purposes and permits a rapid use without danger of.-

catching points in the paper. Mounted on said main pen pointlOl is a second pen point which is preferably placed on the top surfa ce of the main pen, the second pen 13 being arranged so as to slide on the first mentioned penpoint so that it can be moved longitudinally to'force its nibs or writing points 1% either beyond the nibs 12 of the main pen point or to be slid back in rear of said pointsor nibs 12. I The preferred means for holding these. pens insliding relation is to provide strips or. guides15 on the main pen point, these being sufficiently high to permitthesecond pen point 13 to slide underneath them, the strips ofguides lo being preferably struck up from the main pen point and of a width to prevent the undue side or transverse movement of thesecond pen point on the main pen point. Furthermore, one of the guides canjbe used as a means for coacting with the second pen point to limit'the forward movement of said second-penpoint by reason of the engagement of a suitable finger piece 16 which is preferably arranged on the back edge of the,

second pen and projects far enough above the surface of the pen'so that it can be engaged by the finger nail and can be thus 0perated without soiling the fingers, as will be evident.

The finger-piece 16 is usually mounted on a strengthening or stiffening strip 17 which engages the back of the strip 15 and also acts as a base or support for the finger-piece 16. I also provide means for limiting the rearward sliding of the second pen point on the first, and this can be accomplished in a number of-ways, one form being shown in the drawing in which the main pen is punched up'to form a projection 18 against which the rear end of the second pen is adapted to be pushed when the second pen is slid-backward so that the movement thereof is limited. It will thus be evident that these pen points are longitudinally slidable in relation to each other and thus sliding movement imparted thereto by the fingers.

It will be understood that the particular forms of nibs can be varied and that the second pen point can be the broad pen point and the main pen the fine point, but the type shown is thought to be preferred, since in ordinary writing with the nibs 12, they, due to their stiffness and broader surface, act to guard the finer pointed pen from any injury. The pens are usually arranged. close together so that they slide one on the other without intervening spaces, thus making the pen one that, does not appear cumbersome and one without undue friction.

Having thus described. my invention, I claim:

1. A writing implement comprising a pair of pen points one being fastened directly to the other so that they are in slidable relation inorder to projecteither one forward of the other.

2. A writing, implement comprising a main pen point with its rear end adapted to secure the pen to a holder, a second pen point, and means independent of the holder for slidablv securing the second pen point on the main pen. point.

3. A writing implement comprising a pair of pen points in nested relation one on the other and held in limited longitudinal sliding relation so that the points can he made alternately available for .writin l. A writing. implement comprising a. main pen point having guidlng and limiting means thereon forward of its rear end, and

a second pen point in said guiding means and adapted to he slid therein so as tobe projected beyond the main point or caused to retreat in rear of said main point.

5. A writing implement comprising a main pen point having strips projecting from the back thereof, a second. pen point resting against the top of the mainpen point and sliding in the strips, the second point being arranged so that, it canbe slid to either force its nibs beyond the nibs of the main pen point or to cause them to retreat in rear of the nibs of the main pen point,

and. a lingeriece by means of which said second point can be slid;

6. A writing implement comprising a main pen pointhaving strips on. theback thereof, and a projection. in rear of said strips, a second pen point sliding in the strips and adapted to have its rear edge in contact with the projection to limit the back wardmovement of the second pen point, and

a ringer-piece on the second point and adapt 1 ed to engage one of the strips to limit the forward movement of said. second pen point.

7. As a new article ofmanufacture, a

pen point, a slideway on the back thereof,

and a second pen point slidable in said slideway.

8. A pen point adapted to be received and held in a holder, and a second pen point slidably supported on the first-named pen point and adapted tobe supported thereby independently of the holder. r

9. A pen point comprising a large pen 7 point, and a smaller penv point, the smaller b81112 slidable on the larger and both. adapt ed to be supported in a pen holder by insert-1 ing the butt of the larger one onl in the holder.

In testimony that I claim the-foregoing,

'I hereunto set my hand, this 8th day of March, 1915.
